Copper Nickel Flange

TS maintains a broad inventory of Copper Nickel C70600 (90/10) and C71500 (70/30) flanges. Copper Nickel has proven to be very resistant to seawater, brine water, organic compounds, salts, diluted non-oxidizing acids, and more. Due to a high resistance towards marine organisms such as barnacles, Copper Nickel is commonly used in seawater piping systems.

TYPICAL APPLICATIONS

- Seawater piping systems

- Pressure vessels piping outlets

Copper Nickel Weld Neck Flanges

TS, as one of the world-class copper nickel flanges manufacturer and supplier, also produce copper nickel weld neck flanges.

TS copper nickel weld neck flanges are a kind of copper nickel flanges, which refers to a flange with a weld neck and transition of a round pipe welded to the pipe.

The difference between copper nickel weld neck flanges and copper-nickel slip flanges is that there is a long, inclined high-necked flange between the flange and the pipe-welded part of the flange, and the wall thickness of this high-necked part.

The gradual transition to the wall thickness in the height direction improves the discontinuity of the stress and thus increases the strength of the copper-nickel flange.

TS copper nickel weld neck flanges are mainly used in harsh working conditions, such as pipes where the pressure or temperature fluctuates greatly, such as high temperature and high pressure, when the stress on the flange is increased due to thermal expansion of the pipe or other loads. Subzero temperature pipeline.

The copper-nickel weld neck flange is not easy to deform, or sealed, and is widely used. The nominal pressure is about PN1.0MPa~PN25.0MPa.

TS copper nickel weld neck flanges can be divided into the following types according to the sealing surface: flat face flanges, and raised face flanges.

Copper Nickel Socket Weld Flanges

TS, as one of the world-class copper nickel flanges manufacturer and supplier, also produce copper nickel socket weld flanges.

TS copper nickel socket flange’s basic shape is the same as copper-nickel slip-on flanges. That is, a certain borehole is formed in the inner hole of the copper-nickel flange.

The pipe is inserted into the borehole and welded.

Welding a circle of welds on the back of the flange, due to gaps between the socket flange and the groove, easy to produces corrosion,

if a seam is welded inside to avoid such corrosion.

TS copper nickel socket weld flanges welded on both inner and outer sides have a fatigue strength that is 5% greater than copper-nickel slip-on flanges and has the same static strength.

When using a copper-nickel socket weld flange, its inner diameter needs to be the same as the inner diameter of the pipe. The socket weld flange is only suitable for pipes with a nominal diameter of 150 ( 4 inches) or less.

Copper Nickel Threaded Flanges

TS, as one of the world-class copper nickel flanges manufacturers and suppliers, also produces copper nickel threaded flanges.

TS copper-nickel threaded flanges are made by machining the inner bore of a flange into a pipe thread and are connected to a threaded pipe to make a connection.

This is a non-welding flange. Compared with the copper-nickel weld neck flanges and copper-nickel slip-on flanges, the copper-nickel threaded flanges are easy to install and maintain and can be used on pipelines that are not allowed to be welded on-site.

But in the pipeline temperature changes sharply or the temperature is higher than 20 °C below -45 °C conditions. We do not recommend using the copper-nickel threaded flange to prevent leakage.

Threaded Type: NPT, BSPT

The sealing surface of the copper-nickel threaded flange has two types, raised face and flat face.

Take into account the structural characteristics of the copper-nickel threaded flange.

Therefore, it is not suitable for flammable/explosive and highly hazardous and extremely hazardous applications.

Nuclear pressure is small, such as air-conditioning water systems, etc., which can be used safely.

Copper Nickel Blind Flanges

TS, as one of the world-class copper nickel flanges manufacturer and supplier, also produce copper nickel blind flanges.

The middle of the blank flange is solid, surrounded by bolt holes, copper-nickel blind flanges can be either flat or raised.

Copper Nickel Blind Flanges

In short, the purpose of copper-nickel blind flangs is to block the copper-nickel pipeline, it is the material inside the pipe that will not overflow, generally used at the end of the water supply branch.

There is a temporary part of the pipe segment to be used for the temporary blockade, some directly with the valve, some of the original pipes is now unused, use copper-nickel copper nickel blind flanges.
